18K YELLOW GOLD AUTOMATIC GENTLEMAN’S WRISTWATCH, REF 6440
One of the most highly-coveted timepieces from the mid-20th century, the reference 6440 — affectionately known as the Cioccolatone among collectors, due to its resemblance to a square of chocolate — utilizes one of the first automatic calibers created by Vacheron Constantin.

The lot is sold in the condition it is in at the time of sale. The online condition report is provided to assist you with assessing the condition of the lot and is for guidance purposes only. The images of the lot also form part of the online condition report for the lot provided by Sotheby's. Any reference to condition in the online condition report does not amount to a full description of condition. The online condition report may make reference to particular imperfections of the lot but you should note that the lot may have other faults not expressly referred to in the online condition report of the lot or shown in the online images of the lot (for example, the online condition report may not specify mechanical replacements or imperfections to the movement, case, dial, pendulum, separate base(s) or dome). Watches in water-resistant cases have been opened to examine movements but no warranties are made that the watches are currently water-resistant. The online condition report may not refer to all faults, restoration, alteration or adaptation because Sotheby's is not a professional conservator or restorer but rather the online condition report is a statement of subjective, qualified opinion genuinely held by Sotheby's (for example, information regarding colour, clarity and weight of gemstones are statements of opinion only and not statements of fact by Sotheby's). Please also note that we do not guarantee the authenticity of any individual component parts, such as wheels, hands, crowns, crystals, screws, bracelets and wrist bands, since subsequent repairs and restoration work may have resulted in the replacement of original parts. In addition, certain images of the lot provided online may not accurately reflect the actual condition of the lot (for example, the online images may represent colours and shades which are different to the lot's actual colour and shades). For these reasons, the online condition report is not an alternative to taking your own professional advice regarding the condition of the lot.
